Colombian authorities are probing whether any of the women involved in the prostitution scandal that’s cost six Secret Service agents their jobs were underage, according to a new report.

Investigators from the Colombian attorney general’s office have talked to employees of the Hotel Caribe, where the agents were staying, and have questioned the taxi driver who drove home Dania Suarez, the hooker at the center of the scandal, a Colombian government official told McClatchy Newspapers.

Police officers also visited the Pleyclub, one of the adult entertainment clubs linked to the scandal, to verify the ages of the women who worked there, a club employee said.
